Technical Parameters
Technological Process
The machine group is equipped with 5 groups of paper roll holders, and the paper reel adopts air swelling shaft,which is convenient to operate and accurate positioning. Each paper holder is equipped with an axial adjustment device to adjust the paper roll to the correct position;
Standard brake belt to control paper tension (magnetic powder brake control device can be added); Put the spare paper roll in the empty holder, and use adhesive tape to glue it with the paper roll that is about to run out, to realize fast paper change;
The first paper roll holder is equipped with a guiding control device to locate the position of the paper tape
Rectification mechanism
Keep the paper tape along the scheduled running path to ensure the accurate operation of the after process and stabilize product quality, thereby improving efficiency and saving materials;
Adopt a four-layer structure, each layer is equipped with two parallel rollers, the rollers can be driven by servo motors according to a certain angle to move left and right, and equipped with sensors to detect the edge of the paper tape to control the position of the roller and then correct the position of the paper tape, so that the paper tape is guided in the correct position required by the paper bag cylinder;
Guide the operation of each layer of paper tape, correct the lateral deviation, convenient to operate.
Horizontal glue doting mechanism
At both ends of the piercing line (the upper and lower parts of the paper bag cylinder), the multi-layer paper tape is glued to glue the multi-layer paper into a layer of integral paper tape, so that the subsequent gluing machine can be separated from the innermost layer when opening the mouth of the paper bag;
The horizontal step glue dispensing mechanism is composed of dispensing body,glue roller and glue homogenizing roller;
The dispensing body is equipped with a circular arc dispensing board, plastic connection sinstalled on the dispensing board and a rubber head,and the position of the rubber head can be adjusted to adapt tothe paper tube dispensing of different steps;
The amount of glue can be adjusted by adjusting the spacing between the glue roller and the glue dispensing body, and the rubber homogenizing roller.
